OfficeXP Icons Are not highlighted properly

Not really a bug, but a feature request: In Office XP style (and likely Office 2003 style also), when highlighted, icons should be "raised" (nudged up and left by 1 pixel), display a shadow and have enhanced contrast. Pressed buttons (holding the mouse button over a button, for example) should retain the enhanced contrast. As an alternative, the commandbar should support multiple imagelists (one for "hot" buttons and another for disabled buttons, in addition to the normal one) and draw the button from the appropriate imagelist.
